NITED STATES PATENT OFFICE.

ALBERT GUMMER, OF OMRO, WISCONSIN.

VEHICLE-SPRING- SPECIFICATION forming part of Letters Patent No..253,201, dated. February '7, 1882.

Application filed December 31, 1880.

To all whom it may concern Be it known that I, ALBERT GUMMER, of Ornro, Winnebago county, Wisconsin, have invented certain Improvements in Vehicle- Spriugs, of which the following is a specification.

The nature of my invention relates to the use and peculiar construction of a vehiclespring by centrally combining an elliptic or full spring and a semicircular half-spring together,in which combination the elliptic spring is centrally connected to the vehicle-body, ora projection thereof, on one side and within the curve of the half-spring on the opposite side, and used for the purposeof sharing the weight of the vehicle-body and as an equalizer to the same, to prevent a longitudinal or lateral play of the vehicle-body as it bears upon the ends ofthe half-spring, to which the same is connected by jointed studs or couplings. Each of the springs forming the combination is made of one or more leaves, and the leaves of the half-spring are bent in the direction covering the elliptic spring to unite with the jointedstuds fastened to the vehicle-body.

In this arrangement full freedom of action is given to the half-spring, and an improved bearing capacity, combined with a proper flexi- (ModeL) which it is connected. 40

D are jointed coupling-studs connecting the vehicle-body A with the ends of the halfspring 0.

I claim- An elliptic spring, B, centrally connected to 5' the vehicle body A, or a projection thereof, on one side and within the curve to the halfspring (3 on the opposite side, in combination with jointed coupling-studs D, substantially as shown and described, and for the purpose 50 set forth.

ALBERT GUMMER.
